. Black Americans are, on the whole, about twice as likely as White Americans to develop high blood pressure. This likelihood also holds for westernized Black Africans when compared to White Africans.
Researchers have hypothesized that this predisposition in westernized Blacks may reflect an interaction between western high-salt diets and genes that adapted to an environmental scarcity of salt.
Which of the following statements about present-day, westernized Black Africans, if true, would most tend to confirm the researchersâ€™ hypothesis?
(A) The blood pressures of those descended from peoples situated throughout their history in Senegal and Gambia, where salt was always available, are low.
(B) The unusually high salt consumption in certain areas of Africa represents a serious health problem.
(C) Because of their blood pressure levels, most White Africans have markedly decreased their salt consumption.
(D) Blood pressures are low among the Yoruba, who, throughout their history, have been situated far inland from sources of sea salt and far south of Saharan salt mines.
(E) No significant differences in salt metabolism have been found between those people who have had salt available throughout their history and those who have not.

Lists of hospitals have been compiled showing which hospitals have patient death rates exceeding the national average. The data have been adjusted to allow for differences in the ages of patients.
Each of the following, if true, provides a good logical ground for hospitals to object to interpreting rank on these lists as one of the indices of the quality of hospital care EXCEPT:
(A) Rank order might indicate insignificant differences, rather than large differences, in numbers of patient deaths.
(B) Hospitals that keep patients longer are likely to have higher death rates than those that discharge patients earlier but do not record deaths of patients at home after discharge.
(C) Patients who are very old on admission to a hospital are less likely than younger patients to survive the same types of illnesses or surgical procedures.
(D) Some hospitals serve a larger proportion of low-income patients, who tend to be more seriously ill when admitted to a hospital.
(E) For-profit hospitals sometimes do not provide intensive-care units and other expensive services for very sick patients but refer or transfer such patients to other hospitals.

A for this. Only this compares the blood pressure levels of black people in America originally from Africa where salt is low.

A for this as well.
POE - everything else seems right.

OA is A. But I picked D because I thought the whole point was that salt was unavailable to original african blacks from africa.

1: D.
The author concludes that high salt-diet --> high blood pressure:
D support this conclusion by stating that with a low salt diet, the Yoruba had a very low blood pressure.

2: C
Because The data have been adjusted to allow for differences in the ages of patients: C states information regarding age which is eliminated in the data.
Thus C is the best.

I was down to A and D and I picked D because it is about the past people.

[quote="rianah100"]. Black Americans are, on the whole, about twice as likely as White Americans to develop high blood pressure. This likelihood also holds for westernized Black Africans when compared to White Africans.

==========
Got A here.
The question basically says, that the conclusion is based on the fact that 'an interaction between western high-salt diets and genes that adapted to an environmental scarcity of salt'.
A supports this by saying that there is evidence to this fact.
